I've seen a number of posts inquiring about removing all data from a feed but keeping the feed, but I've never seen it answered. Is there a way to do it via GUI or from a command line (via curl, for example)?
It comes up frequently for me - like I make a change to the program and then I have all this stale data and the plot scale is goofy or I move the sensor from testing into 'production' and the same thing happens. Removing the entire feed and recreating it isn't convenient.
Thanks,
Brecky

Re: Clear all data points in a feed?
Hi Brecky,
There's no way to remove all data from a feed at once. Feed deletion is an API action (https://io.adafruit.com/api/docs/#delete-data-point) and is therefore limited to your account's data rate (30 or 60 data points per minute for IO Free and IO Plus, respectively).
You may want to create a script which uses the delete data point api endpoint (https://io.adafruit.com/api/docs/#delete-data-point) to remove data.
I'll put a feature request in for the devs., it's something I'd like to see too.

Re: Clear all data points in a feed?
I'd love to have this feature too. I have a feed in which the sensor was not correctly connected for a while and it now has a bunch of invalid data. It is throwing off the charts now, and I'd like to just reset the feed to empty. I could delete the feed but I guess it would probably remove it from my dashboards.

Re: Clear all data points in a feed?
Found a workaround for clearing all data from a feed. Go to your feeds and delete all of them related to your sketch. Wait for your update period and magically, your feeds will re-appear!
From what I have observed, there is no need to re-create your feeds, them seem to be in the system even after you delete them.

The Adafruit IO Arduino library can programmatically create feeds from your sketch, if they do not already exist on your IO account.
